The intent of this credit is to alter planting details to eliminate the use of potable water for landscape irrigation as much as possible. Project teams tend to interpret "landscape" as any vegetated space on the project site. However, some projects also include growing space for food in an urban agriculture or community garden setting. This is not "landscape" in the usual sense, and the normal water use reduction measures aren\'t appropriate when the land is being used productively. In LEED for Homes, an existing LEED Interpretation clarifies that growing space should be exempted entirely from the calculations for the Homes version of this credit (do not include in the numerator or denominator). See LI 2736. I request that this LI be extended to all LEED rating systems, since growing space is potentially a component of many project types.
Project teams may elect to exclude food gardens from landscape calculations on the rationale that normal water use reduction measures are not appropriate when the land is being used to produce food for human consumption. If a project team chooses to exclude a food garden from the landscape area, it should be excluded uniformly across the baseline and design calculations.
